VisionPads＆#8482; have significant performance advantages over other pads in copper barrier processes:

• Retain peak performance throughout life of pad
• Higher wafer yields due to low defectivity results during volume production of copper wafers
• Superior chemical mechanical planarization performance
• Improved die yields through minimization of scratches across the wafer
• End point detection available
